A320 and aerodynamic center
I wonder what is the location of the aerodynamic center in A320, considering it is a subsonic aircraft..
most of the books on the aerodynamics says that AC of a subsonic aircraft is about quarter-chord. so it be for A320 also ... but the aft CG limit in flight of the A320 is 45%. for positive longitudinal stability CG should always be ahead of the AC. it means that aerodynamic center in A320 lies beyond 45% chord... could that be true?

thanks in advance
